PIPEFITTING SECURING TOOL This invention relates generally to tools for securing fittings upon soft plastic pipe.

The principal object of the present invention is to provide an improved tool for the purpose of applying fittings, such as adapters, reducers, elbows, tees and couplings to different sizes of soft plastic pipe.

Another object of the present invention is to provide a tool for applying fittings upon soft plastic pipe wherein there are a pair of rubber-lined jaws that form the pipe-holding clamp.

Other objects of the present invention are to provide a tool which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

The sole FIGURE is a perspective view of a mechanism comprising the tool invention.

Referring now to the drawing in detail, the reference numeral represents a tool according to the present invention wherein there is a frame 11 having a guide slot 12 therein, the frame 11 having a sidewardly projecting arm 13 rigidly secured thereto by means of a weld or the like.

One end of a lever 14 used for the purpose of applying pressure to fittings, is secured pivotally free by means of a pin 15 to the arm 13. A rubber handgrip 16 is secured to the opposite end of the lever 14 so that the same may be manually operated.

A cradle 17 of U-shaped configuration and used to hold and guide the fitting is secured on its underside to a channel configurated guide 18, and having a pair of downwardly extending pins 17A, the pins straddling the lever 14 and extending downwardly into the slot 12 of the frame 11.

A part 19 having reversible ends, used solely for pushing the fittings, is positioned over the cradle 17. The reversible part comprises a generally rectangular member of framelike character having a slot on one side thereof, and the terminal ends adjacent to the slot being inwardly pointed to a central area 20 within the framelike structure.

A main handle 21 is secured at one end upon the frame 11, the same end of the main handle having a semicylindrical jaw 22 secured thereto, the jaw 22 having a rubber lining 23 on the inner side thereof. A moveable jaw 24 of semicylindrical configuration is likewise provided with a rubber lining 25, the jaw 24 being pivotally attached to jaw 22 by means of a hinge 26. A U-shaped bar 27 is rigidly affixed to the upper jaw, and a ring 28 surrounds the bar 27.

A clamp lever 29 provided with a rubber handgrip 30 at one end is centrally provided with a pair of lugs 31 for receiving a pin 32 therebetween, the pin 32 engaging one end ofa link 33,

the opposite end of the link being fitted into a slot 34 of a frame 35 mounted upon the main handle 21, the opposite end of the clamp lever being connected to the ring 28 and an end of a link 36 by means of a weld, the link 36 having the lower end thereof within the slot 34. The link 36 is slidable in slot 34 toward a corner thereof.

A spring 37 for the purpose of maintaining the jaws in a separated open position, is located between the clamp lever and the bottom of the slot 34 of the frame 35. A clamp lever adjusting screw 38 threadingly engaged within the end of the frame 35 bears against one end of the link 33, the clamp lever adjusting screw having a flathead 39 for manual manipulation thereof.

Thus there has been provided a tool for the purpose of holding a soft plastic pipe while a fitting such as an adapter, reducer, elbow or tee is secured to the end thereof.

While various changes may be made in the detailed construction, it is understood that such changes will be within the spirit and scope of the present invention as is defined by the appending claims.

What I now claim is:

1. In a tool, for the purpose of applying fittings to different sizes of soft plastic pipe, a combination of a frame, said frame having a slot therein, said frame having a sidewardly extending arm welded thereto, one end of a lever being pivotally attached by means of a pin to the end of said arm, said lever being for the purpose of applying pressure to fittings, the opposite end of said lever having a rubber handgrip, and said lever having a cradle secured upon a channel positioned above said frame, said channel comprising a guide having two vertically extending pins which straddle said lever, said pins extending downwardly into said slot of said frame, a main handle being secured at one end upon said frame, said main handle having at one end a semicylindrical jaw secured thereto, said jaw having a rubber lining, a movable jaw hingedly secured to said semicylindrical jaw which is stationary respective to said main handle, said movable jaw having a likewise rubber lining upon the inner side thereof for placement against a plastic pipe, a box being mounted upon said main handle, said box receiving one end of a link slidably fitted thereinto, said link being integral with a ring carried on a U-shaped bar rigidly secured to said movable jaw, said link being integral with a clamp lever, the opposite end of said clamp lever having a rubber handgrip, a pair oflugs mounted upon said clamp lever between said rubber handgrip and said link thereof, said lugs having a pin extending transversely therethrough and supporting pivotally free one end of a second link, the opposite end of said second link being fitted into said box, a clamp lever adjusting screw threadingly engaged to said box and bearing against said end of said second link, and a part with reversible ends for pushing fittings in position over said cradle.
